+===== Introduction =====
+**WIO** is the abbreviation for **W**ireless **I**/**O**.\\
+ \\
+===== General I/O =====
+The general purpose I/O is comparable with the Pi02/GCA50/CANGC2, using WiFi as wireless communication 'bus' instead of wired I2C/LocoNet/CAN, and
+is compatible with all known __**[[:hardware-en#extension_units|GCA Extension Units]]**__.\\
+The main part of the needed I/O settings are defined in Rocrail, which makes a hardware swap al lot easier.\\
+ \\
+===== Throttle =====
+{{ :arduino:wioctrl-display.jpg?200}}
+The throttle supports the following configuration:
+  * Rotary for speed, direction and selection of loco and function.
+  * Up to 6 push buttons for functions and selection.
+  * Display.
+| Only the ESP32, Lolin D32, is supported. |
+The in Rocrail defined locomotives can be transferred to the throttle(s) by __**[[:rocgui-menu-en#transmit_short_ids|sending the Short IDs]]**__. (Up to 256)\\
+ \\
+===== Options =====
+==== Standard ====
+The General I/O is controlled by the I2C bus.(MCP23017) This I2C bus can simultaneous be used for:
+  * Two I/O Expanders MCP23017 (32 I/O)
+    * ESP32 and PicoW up to 4 MCP (64 I/O)
+  * Two displays, compatible with RocDisplay.
+  * One Sensor for temperature, humidity and pressure.
+  * One Sensor for light.
+  * Two 7-Segment display for time, date, temperature and simple dynamic text.
+  * Play wave files in case of the LOLIN D32 with on board DAC output. (Digital Analog Converter)
+==== Extra ====
+Extra options, which needs accurate timing, are __mutual exclusive__:
+  - 64 LED chips control like the WS2812. (128 on PicoW)
+  - Four Servos.
+  - Two RC522 RFID readers.
+  - __**[[:arduino:wio-dcc-en|DCC Command Station]]**__.
+  - Mobile PWM motor control.
+  - CAN interface for 125/250kB standard/extended frames on TCP port 5550. (Binary)
+  - CAN Node in a RCAN compatible system, not using WiFi.
+==== Serial RS232 ====
+The serial options are also __mutual exclusive__:
+  - Monitor.  (default)
+  - RailCom reader.
+  - Mobile RFID reader.
+==== I2C RocNetNode ====
+The following RocNetNode boards are compatible with WIO:
+^ Unit ^ Description ^ I2C Address(es) ^ Remark ^
+| [[:gca_pi02-en|Pi02]] | 32 I/O | 0x20, 0x21 | Only on WIOs without MCP23017 on board. Must start with 0x20. |
+| [[:gca-pi03-en|Pi03]] | 16 Servos | 0x40 | This will deactivate the Servo option, and can be used in combination with other options. |
+| [[:gca-pi06-en|Pi06]] | Power supply and I2C HUB | - | For use in combination with the WIO-I2C. |
+| [[:gca-pi08-en|Pi08]] | 16 Dimming LEDs | 0x60...0x67 | Max. 8 units; 128 LEDs. This will deactivate the FastLED option. |

+===== Kits & PCBs =====
+[[:hardware-en#wio|The following Kits are available:]]
+====WIO I/O====
+For all basic functionality except throttle.\\
+Features all needed connectors for all options.\\
+====WIO Boost====
+Specially for Option DCC with integrated 3A booster. (H-Bridge)\\
+====WIO Prog====
+Same as the WIO Boost but with an extra H-Bridge for Service Mode, Programming Track.\\
+====WIO Drive====
+Specially for Option DCC and Mobile with integrated 3A booster. (H-Bridge)\\
+__Note:__ Not compatible with the WEMOS D1 Mini; Won't boot. Use a LOLIN D1 Mini only for the WIO-Drive.\\
+====WIO VC1====
+Command Station with booster from 1.6 to 20A.\\
+====WIO Control====
+A throttle based on LOLIN D1/D32 with display and rotary.\\
+See __**[[:arduino:wioctrl-en|WIO Control]]**__ for functional information.\\
+====WIO CAN====
+WiFi MBUS/RCAN interface.\\
+====WIO I2C====
+Simple module with I2C buffer which connects to the [[:gca-pi06-en|Pi06]].\\
+====WIO Clock====
+(Fast) Clock for 4" 7-segment displays controlled by PCA9622. (IO_CLOCK option in the USERCNF.h)\\
+The time will be synchronised in case the NTP_CLOCK option is activated in the USERCNF.h.\\
+====RailCom Reader====
+A separate amplifier kit, GCA214, is available for reading RailCom data.\\
